Product catalog summary
Technical Document Summary
1. Specifications
This document provides detailed specifications for Bosch Rexroth hydraulic cylinders, specifically models CDH1, CGH1, and CSH1. It includes dimensions for cylinders with piston rod extensions, trunnion mounting, and foot mounting. Key parameters such as piston diameter (ØAL), piston rod diameter (ØMM), and stroke length (X*) are specified. The document also outlines maximum and minimum stroke lengths, thread designs, and flange connections.
2. Procedures
Installation instructions emphasize the importance of ensuring trunnion bearings are installed up to the trunnion shoulders to avoid reducing the product's service life. The document also provides guidance on bleeding procedures and the positioning of line connections relative to the piston rod.
3. Standards and Norms
The document references several ISO standards, including ISO 9013 for thermal cutting tolerance classes and ISO 6162-2 and ISO 6164 for flange porting patterns. These standards ensure compatibility and performance consistency across hydraulic systems.
4. Recommendations
Recommendations include specifying the "XV" dimension when ordering and observing the trunnion position in the cylinder center. The document advises on the use of throttle valves with end position cushioning and highlights the importance of adhering to specified dimensions and tolerances.
5. Key Data from Tables
The tables provide detailed dimensions for various cylinder sizes, including piston and rod diameters, stroke lengths, and connection specifications. They also list maximum operating pressures for related flanges and provide porting patterns for valve mounting.
6. Critical Information
Critical information includes the need to observe minimum stroke lengths, the importance of proper installation to maintain service life, and the necessity of specifying correct dimensions for ordering and installation. The document also highlights the limitations of certain seal designs for static holding functions.

2/74 Bosch Rexroth AG | Hydraulics Standards: Bosch Rexroth standard; main dimensions like piston 0 and piston rod 0 correspond to ISO 3320. Static test pressure: 375 bar Reduced test pressure: 315 bar The maximum operating pressures must be less than or equal to the applicable nominal pressures and apply to applications with shock-free operation with reference to excess pressure and/or external loads. With extreme loads like e.g. high sequence cycle, mounting elements and threaded piston rod connections must be designed for durability. Minimum pressure: Depending on the application, application...

Hydraulics | Bosch Rexroth AG Technical data (For applications outside these parameters, please consult us.) Boundary and application conditions: • The mechanical alignment of the movement axis and thus the mounting points of hydraulic cylinder and piston rod must be ensured. Lateral forces on the guides of piston rod and piston are to be avoided. It may be necessary to consider the own weight of the hydraulic cylinder (MP3/MP5 or MT4) or the piston rod. • The bending length/bending load of the piston rod and/or the hydraulic cylinder must be observed (see page topic Kinking). • The maximum admissible...
